IMPROV'BD GAS-APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES H'. CHILDS, ofCIeveIand, in the county of Cuyahoga, and Stateof Ohio, have invented certain new and useful Improvements ina Gas-Apparatus; and I do hereby declare that the following is a. full and complete description of the same, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is a side view of the apparatus. Figure 2 is a top view of'the inside. Figure 3 is a view ofthe under side of the receiver. Figure 4, a vertical transverse section. 4 Like letters of reference refer to like parts in the diierent views. In g. 1, A is a metallic case, the size of which being according to the capacity of the machine required. vWithin this case, and secured to the bottom ofLthe same, is a lining or cylinder, B, the diameter of which, being` much smaller than that of the case, leaves an annular space or chamber, C, between the walls of the two, and in which is fittedaiioat or meter-cover, D. Within this cylinder is fitted the air-chamber E, atop view of which, and an inside view of the bottom, is shown in tig. 2. vThis chamber is constructed with an inner and outer wall, making a wide annular space, F, between them, which, it will be seen, does not reach to the bottom of the case A, but stops at the diaphragm-G, which forms the bottom of the air-chamber E.

The outer wall of-the chamber continues down to near the bottom of the case, dividing the lower part into asection or chamber, G.

The chamber E is put in communication with the lower part, G, by means of tubes, H, iig. 2, alsoindicated by the dotted line ci in iig. 4. These tubes are constructed of perforated sheet metal, and are wrapped in cotton wicking, or with other like textile or iiocculcnt material, I; also ropes, of the same material, are drawn around and through the tubes, with their upper ends projecting above the diaphragm, as shown at J, iig. 4. The position of these tubes, with their covering and filling, is also shown in iig. 3, which represents the bottom of the chambers E F.

. Leading from the outside of the case A to the chamber E is an air-pipe, M, which, it will under and through the bottom ofthe case, Aand terminates in one ofthe tubes H, referred to.

N is an eduction-gas pipe, leading from the lower section, G', to thel outside of the case,vfrom thence to the burner. I

Having thus described the construction and arrangement of the apparatus, the practical operation of the same is as follows: i p

The air-clizltmbeil E, when the apparatus is together, as shown in iig. l, is charged with air, by raising up the ioat or cover D, which causes a vacuum to form in the chamber. The air is allowed to pass into the cham ber by turning the stop-cock O, which on being fully filled is then closed. The annular chamber F is charged with naphtha, gasoline, or with any of the products of the distillation of petroleum. From this chamber it is allowed to ow into the lower section, G', so as to cover the bottom i'or a few inches in deptlnf p The textile materials being partially immersed in the fluid, soon become saturated therewith, and thus the gaseous and volatile elements oi' the iluid are evolved, and disseminated above the bulk of the iiuid.

The gas thus evolved, and the inducted air, are prevented fromescaping by the space G, between the out side case, A, and cylinder or lining B, being filled with water, and in which the float is immersed.

` Now, as the float is forced down, by weights being placed upon it, or by any other mechanical appliance, the air is forced from the chamber E, through the tubes H, int-o the section G below, where it becomes charged with the gases eliminated from the fluid.

The air thus treated becomes highly illuminous, and escapes from the apparatus through the pipe N to the burner, as before said. p t

'What I claim as my improvement, and desire to secure by Letters Patent, is 1. The perforated tubes II, surrounded with textile or fibrous material, and chamber C', in combination with the chamber E and annular space F, substantially as and for the purpose specified.

2. The pipes M N and chamber C', in combination with the' diaphragm Gr, annular chambers C. and cover D, arranged as and for the purpose set forth. V

be seen, passes CHARLES H. CHILDS.
